AVC
Any Video Converter: It is named as AVC by shortcut. It is the fastest Free Multimedia converter by my choice. You can set the priority to HIGH by going to Edit\Option from it's menubar.
There's a editing option too. You can crop, cut a video also.
If you want to convert a video for mobile size give settings like below. It is fine for a mobile screen. I called it low size AVI.

iSkysoft converter
Download iSkysoft converter first. It is very fast. You can called it as super fast also. It is more & more faster than Xilisoft. It has the ability to cut or edit also. You will miss a lot if you don't download & check this out. Now i am using this as i didn't inserted PCI express card into my PC. All the converter will fail to it's power & work priority. It has too many profile (saved before) for you to work without trouble. You don't have to give settings of every profile name. I am using it for 2 years without any problem. You have to just disable it's CHECK FOR UPDATE feature once , nothing more.
